1213 ETN9/C3 Bearing Product Overview & Core Advantages
The 1213 ETN9/C3 is a double row angular contact ball bearing engineered for demanding applications requiring high load capacity and operational stability. This precision bearing is designed to accommodate significant combined loads, simultaneously handling radial forces and axial loads in both directions. Its compact double row design offers a high degree of rigidity in a relatively narrow cross-section, making it an ideal solution for high-reliability machinery. The bearing comes pre-lubricated and features an optimized internal geometry for smooth, efficient performance.
1213 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| E | Optimized internal design | Increased load rating and improved operational performance. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Reduced friction, excellent for high-speed operation, and good acceleration characteristics. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads. |
1213 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior stiffness, enabling the bearing to withstand heavy combined loads (radial and bidirectional axial) without significant deflection.
- Optimized High-Speed Performance: The lightweight and durable TN9 nylon cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 7,000 rpm. The pre-lubrication ensures smooth operation from startup.
- Operational Reliability: The C3 radial internal clearance is selected to prevent pre-loading under operational thermal expansion, ensuring consistent performance and extended service life in variable temperature environments.
- Material Integrity: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent durability and resistance to wear.
1213 ETN9/C3 Bearing Typical Application Areas
This bearing is suited for a wide range of industrial machinery where high rigidity and combined load capacity are critical. Common applications include:
- Industrial Gearboxes and Transmissions
- Pump and Compressor Shafts
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust support
